Dota 2 remains one of the most attractive titles on Steam, drawing a peak of 542,906 concurrent users today. The second most popular title is also a Valve production – Counter-Strike: Global Offensive with 93,905 peak concurrent users.

The Elder Scrolls V; Skyrim, Sid Meier’s Civilization V and Football Manager 2013 are the next most popular, which is deeply unsurprising.

Steam’s sudden jump in users may be partially explained by its holiday sale, and is in defiance of the launch of two new consoles, the PS4 and Xbox One, which might have been expected to draw users away from their PCs.
